Red Hat Bugzilla – Bug 131885
There is an updated microcode for ia32 CPU's
Last modified: 2015-01-04 17:09:28 EST
Description of problem:
The kernel-utils package contains ia32 microcode released May 1 2001,
but there is at least two microcode file released in 2004.
I rolled my own kernel-utils using the 1.09 microcode_ctl (as the site
says, the app itself is unchanged, it just includes the updated
microcode.dat file) and it worked fine on my system:
microcode: CPU0 updated from revision 0x35 to 0x39, date = 06042003
I can't tell any difference, but it's newer so it must be better :)

went out into updates-testing today, will go to live updates real soon.
Please note that the microcode has been updated again. See: http://www.
urbanmyth.org/microcode/, or get http://www.urbanmyth.org/microcode/
microcode_ctl-1.12.tar.gz for the actual code.
Thanks on behalf of those of us whose motherboard vendors won't provide updates.
